## SA 501 – Inventory: Existence & Condition
### Why This Matters
When inventory is material to the financial statements, the auditor must obtain Sufficient and Appropriate Audit Evidence (S&A AE) about its existence and condition. This is one of three specific items addressed in SA 501.
### Primary Procedures
1. Attend the physical inventory count
2. Test the final inventory records to verify they accurately reflect actual count results
---
### Three Special Cases
#### Case I – Unforeseen Circumstances (Auditor Cannot Attend on Scheduled Date)
- Observe physical count on an alternative date
- Perform audit procedures on intervening transactions (between count date and final records)
Key matters to check for intervening transactions:
- Whether perpetual inventory records are properly adjusted
- Reliability of perpetual inventory records
- Reasons for significant differences between physical count and perpetual records
#### Case II – Attendance is Impracticable
(e.g., due to the nature or location of inventory)
- Perform alternative audit procedures to obtain S&A AE on existence and condition
- If alternative procedures are also not possible → Modify the audit report (SA 705)
#### Case III – Inventory Held by a Third Party
Perform one or both of:
1. Request written confirmation from the third party (quantity and condition)
2. Perform inspection or other appropriate audit procedures
Other procedures for third-party inventory:
- Inspect documents such as warehouse receipts
- Request confirmation when inventory is pledged as collateral
- Attend (or arrange another auditor to attend) the third party's physical count
- Obtain another auditor's or service auditor's report on the third party's internal controls

### Matters to Consider When Planning Attendance at Physical Count
1. Nature of inventory
2. Stages of completion of Work-in-Progress (WIP)
3. Internal controls (IC) related to inventory
4. Instructions issued for inventory counting
5. Timing of the inventory count
6. Whether the entity maintains a perpetual inventory system
7. Location of inventory
